XO-Ferg, that's because you used the visual editor. You now need to edit the template (Control Panel -> Customize design -> Video -> Page with full entry text and associated comments), and replace the messed part by the correct code:

And whatever - I have deleted all my previous videos, now I added only 2, but informer shows for me 7 total videos, HOW? ... also for default I press informer edit button for refresh information - nothing - 7 videos, but I have only 2 ..

Second problem:

Why all videos screens show uCoz intro ? hmm.. Before I deleted all ol videos, it was ok, but now - ALL WITH UCOZ INTRO.
